Electrolyte

Electrolytes are minerals in your body that have an electric charge. Common electrolytes include sodium, potassium, calcium, and magnesium. They are essential for nerve and muscle function, hydration, and balancing blood acidity.

Electrolytes are added to foods and beverages to help replenish those lost through sweat, such as during exercise. They are most often found in sports drinks, electrolyte powders, and some juices. Manufacturers add them to improve hydration and taste.

Electrolytes are naturally present in many foods and are also added to some processed foods. The U.S. Food and Drug Administration (FDA) generally recognizes sodium and potassium chloride as safe (GRAS) when used as intended. While essential for health, excessive intake of certain electrolytes, like sodium, can be linked to health concerns. International bodies like JECFA have evaluated various electrolytes.
